Publisher's Synopsis
Excerpt from Relative Resistance of Tree Seedlings to Excessive Heat
The fact that the few references on heat resistance that have been found are taken from observations in the more arid portions of the United States, seems to indicate the close dependence of excessive temperatures upon a dry condition of the atmosphere, and a con sequent aridity of the soil surface. The problem, as understood in this discussion, arises from the great intensity and heating power of sunlight, due both to the aridity and high altitude of much of the Rocky Mountain region. In moister regions the problem is no doubt less serious. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
